Description

Topic:

LinkedIn Search is built on a distributed realtime indexing system, with strong business requirements on SLAs for both search latency as well as how soon a newly updated document is to appear in the search results. Furthermore, with LinkedIn's rich structured information, guided navigation, or faceted search is an important functionality for enhanced user search experience. Combining faceted search and realtime search while maintaining SLA poses challenges in result and indexing cache. We will also discuss other novel solutions for problems such as: section search, e.g. zoning; balanced segment merge for incremental updating indexes; query segmentation and classificaiton etc.
